You can't transfer the programs. They have to be installed from the CD or Download. You don't need to install the prior year programs unless you need to amend that year. Before you move your tax return files make sure you have saved each year as a pdf file. So you may want to open each year and do that. FILE - SAVE TO PDF
What I would do is just copy the whole Turbo Tax folder that is under your Documents. That should be where the .tax files and pdf files are stored. Copy that folder to a flash drive or best yet is to burn it to a CD or DVD and then you will have a backup of them. Then on the new computer copy the folder (or files) from the flash drive to your Documents folder.
You need to have the file ending in .tax2014 to Transfer into the 2015 program.
